The popstar's bandmate Dougie Poynter claimed that the goodwill from his musical wedding speech might be over after the mishap with the ring.
Watch Tom and McFly talk about his lost ring, album six, wedding speeches at the NTAs:
"The YouTube guy lost his wedding ring," joked drummer Harry Judd.
Fletcher said that he had tweeted his wife Giovanna to warn her in advance about the ring in case she thought something was wrong when he appeared at the NTAs.
"I thought she might see me on TV tonight and she might say, 'He's taken his wedding ring off, what's he doing?'" he said.
The boyband also said that the success of Fletcher's wedding speech might mean that it gets a spot on their upcoming sixth album.
"I'm planning a wedding speech tour. 'The Wedding Speech Tour' - It's just me, supported by McFly," laughed Fletcher.
"An acoustic set for half an hour from McFly before I go on with the choir. Look out for that later in the year."

Fletcher, who married girlfriend Giovanna in December, has since been reunited with his wedding ring thanks to his new wife, who posted a picture on Tumblr.
"Call off the search! The ring as been found Xxx," she wrote.
